This paper presents the results of high-strength wastewater treatment by an electro-oxidation method. This high-strength wastewater is produced from refineries during maintenance. The treatment of such wastewater via conventional biochemical processes is a challenging task owing to the high concentration of organic pollutants and the need for an additional pretreatment system. In this study, first, Response Surface Methodology (RSM) with four parameters and three levels was used to design the experiments. The experiments were then carried out under various operating conditions with actual wastewater from a refinery. The dilution ratio (x1), current density (x2), reaction temperature (x3), and reaction time (x4) were found to have significant influence on chemical oxygen demand (COD) removal efficiency. A MATLAB optimization tool was used to find the optimum operation parameters. The optimization results show that the optimum COD removal was 70%. Finally, an economic evaluation, based on the payback period was carried out.
